Plantronics office headset on its charger. In the 1980s, Plantronics created a line of cordless products using infrared technology. Though the technology utilized was the same one being used by television remote controls, the link did not require a Federal Communications Commission (FCC) telecommunications approval. One of the first products ...
After successful sales for the DSP-500 and the Xbox Communicator headsets, [3] In 2004, Plantronics announced the GameCom brand with four new headsets for Xbox Live and Online PC gamers: GameCom X10 and X20 for Xbox Communicator, and GameCom 1 (analog) and GameCom Pro 1 with digital signal processing built-in sound card and connected to a PC via USB port.
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.
Doritos says the software is mostly aimed at gamers who are loath to interrupt their entertainment long enough to eat, interact with their families or engage in any other behavior that might be ...
Most noise-cancelling headsets in the consumer market generate the noise-cancelling waveform in real time with analog technology. In contrast, other active noise and vibration control products use soft real-time digital processing. According to an experiment conducted to test how lightweight earphones reduced noise as compared to commercial ...
In 1957 Willard Meeker developed a working model of active noise control applied to a circumaural earmuff. This headset had an active attenuation bandwidth of approximately 50–500 Hz, with a maximum attenuation of approximately 20 dB. [3] By the late 1980s the first commercially available active noise reduction headsets became available.
Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory .
Adaptive noise cancelling is a signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated [1] [2] [3].
